Bell, linen 1 that l, Acorn: il Ri-ENCIS- SYKES," a subjector" the King of Great Britain, residing at Lorne Ville. New Borneo, Herts, England, have invenied a new and useful Electrical Relay, of which the following is a specification.

This invention relates to electrical relays or the microphone type and is especially on plicnble' for enabling speech Waves to vary the powerful electric currents required for wireless telephony. The invention is, however, capable of being udapleu to various uses and the appliances used in carrying into effect may be varied very Wlflfiljfl According to my invention 1 control-the current'in an electric circuit by the addition to a stream of liquid which forms part the circuit oivorying quantities of an imuritv or conductivit" changer,

Will herein after speck of the liquid as water and of the 'from'the poini- Where ihe soda is introduced should be such to give the soda. suflicient but not too much time to diffuse. through the Water. The electrodes may also bear ranged opposite one another so that the resist-unce of the Water in a transverse direction is utilized, or one may be placed beyond the other, in which case the longitudinal resistance is -the controlling factor.

My invention isillustrcted by the accompanying drawings, Figure 1 i being a sectionol elevation, Fig. 2 a side view, Fig. 3 a. part plan and Figs an end view; Fig.5 is an enlarged viciv'of the nozzle and Figs, 8 and 7 enlarged views of the conduit.

Al? the upper end of the tube is 21 plate 8 having in it a sharp edged orifice. The reservoir and sound-box ore carried by an arm 9 mounted on a pivot 10 the top of a column 11 and provided with :1 depending part 12 held by a spring 13 or st, the point ofan adjustich works in a lug- 15 on the column. arm carries a glass tube 16 which screens the jet cud also o glass plate. 17 throi b which the entry of the jet into the stream con be viewed Without risk of the soda. splashing up into the eyes.

ii) 1S 1 F 51 plied under pressure; its top is closed by a cover 19 clamped down onto an insulating Washer 20 which has at onepoint ii rectum-- gular channel 21 formed in it. In this channel is secured an obstruction, or bzriiie 22 which spliis stream of water so as to form a czivi I therein. Beneath this cavity a hole is'bored in the bed of the channel so chat as the jet passes through the car; 23 and impinges on the downstream ice or the hole nor: is diverted as shown p 7 in ig. 6 and spreading out'on the floor of the channel miug'lcs with the'strea-m while the rest falls down through the hole and runs to waste. The channel beyond the hole is formed of blccks 26 and side plates 27 ill of insulating material. Below the bl'ocks 26 are upper and lower plates 28, 29 which act as electrodes being; in electrical connection with binding screws 30, The stream issuing from the end of the channel pii'sses into a Waste pipe 32. l: have found' that" good results be obtained with 21v stream and jet having a velocity of 100 feet per second. i i

The combination of a source of electi'icity aconduit, means for causing liquid to flow through the conduit, electrodes connected to the source of. electricityend' in Contact with the liquid an aperture in the conduit, an. obstruction in the Jcou-duit Qadapted to form a cavity in the liquid as it passes the aperture, :1 vibratable diaphragm,
